DEMO MANUAL DC2507A

Thermocouple

Connect the thermocouple between terminals 3 and 4 on

terminal block J1, see Figure 13. 1 of 4 sensors can be

used for the cold junction compensation.

CJ Option 1: Active analog temperature sensor (U1) tied

to CH10.

CJ Option 2: Diode (Q1) tied to CH9.

CJ Option 3: 2-wire RTD connected between terminals 1

and 2 on terminal block J1 and assigned to CH4.

CJ Option 4: Thermistor connected between terminals 1

and 2 on terminal block J1 and assigned to CH4.

See pages 63-65 in the LTC2986 data sheet for more

information.

The thermocouple is assigned to CH6 (see Figure 14)

and can be automatically loaded using the con-

figuration file DC2507A_MULTI_SENSOR_BOARD_

THERMICOUPLE_10K_THERMISTOR_CJ or DC2507A_

MULTI_SENSOR_BOARD_THERMICOUPLE_PT100 _CJ

or manually entered using the LTC2986 demonstration

software.
